Dietary supplements from wine vinasses and relevant production process

Abstract

The present invention refers to a dietary supplement containing all of the natural components of wine, except for the volatile ones, in particular ethanol. Said dietary supplement is suitable for oral administration and contains antioxidant complexes present in wine vinasses combined with one or more bioavailability promoters. A preferred embodiment of the invention consists in a dietary supplement provided as solid or liquid formulation allowing for avoidance of wine consumption while maintaining all of the beneficial components, in particular the antioxidant ones.

Description

[0001] The present invention refers to antioxidant complexes derived from wine vinasses, wherefrom solid, semisolid or liquid formulations to be orally used as dietary supplements have been prepared. Said formulations comprise the same antioxidant complexes comprising polyphenolic compounds as contained in wine, e.g. resveratrols, and bioflavonoids, e.g. anthocyanins and polyphenols, but do not contain ethyl alcohol. Therefore, the said formulations do not present the hepatic and central toxicity problems caused by drinking wine to excess while providing for the well known benefits attributed to wine's natural constituents.PRIOR ART[0002] Fruit, vegetables and beverages derived therefrom contain important constituents of the non-energetic diet displaying -antioxidant activity. More than 300 organic compounds belonging to the classes of carboxylic acids, mono- and disaccharides, amines, polyphenolic compounds, volatile compounds and pigments have been identified in wine. The major so...

Benefits of technology

[0007] It is a further object of the present invention to provide an alcohol-free, in particular ethyl alcohol-free, dietary supplement capable of supplying the organism with the antioxidant complexes commonly contained in wine, which are highly useful to the organism itself.

[0009] It is another object of the present invention to provide a process of manufacture of a dietary supplement, which process uses cheap and easily available raw materials and does not alter the antioxidant complexes contained therein.

Problems solved by technology

All of the above compounds are potentially of great biological interest; however, once they are separated from the alcoholic fraction, they have such a reduced bioavailability that they of little use for the organism.

That is the reason why wine vinasses or concentrates thereof cannot be used as dietary supplements capable of simulating the dietetic properties of wine.

Such a constant absorption profile could be hardly obtained through wine consumption itself, since wine should be drunk in small quantities and continually in the space of 24 hours.
